  Status: still open. As of the last comment in this thread (June 3, 2025), no maintainer fix or root cause had been posted; a contributor asked for a screen recording or a reproducible example.

  The only workaround in the thread that worked for someone: a commenter with the same problem switched from a Chromium-based browser (Brave or Opera) to default Google Chrome. Another commenter replied that they already use standard Chrome, and a commenter on a MacBook using Claude Code with default Chrome and a single tab open still hit the error even though /mcp showed the server connected.

  The reported error is Error: No tab with given id <number>. In Claude Desktop it appears after an element reference like {"ref": "s2e245", "element": "Post text textbox"} when composing a tweet on Twitter; in Claude Code it appears after browsermcp:browser_type (MCP)(element: "Email textbox", ref: "s1e21", ...) followed by the same error.

  General advice if you hit this: keep the Chrome profile and window that BrowserMCP controls open for the whole session, don't close or refresh the tab mid-task, and rule out Chrome extensions that might intercept clicks. If it still fails, reproduce it on a minimal page and file an issue with the exact prompt, browser version, and the tab ID from the error.

  What a GitHub user tried on GitHub (Outcome unclear)

  The reporter used BrowserMCP with Claude Desktop and observed clicks failing about 50% of the time on buttons and input fields; no fix was attempted in the initial report.

  What @haenswoerst tried on GitHub (Didn't work)

  A commenter reproduced the failure on Twitter ('compose a tweet'): the mouse hovered over the input field but the click failed, and Claude returned 'Error: No tab with given id 515612901.'

  What @isi2010 tried on GitHub (Didn't work)

  A Claude Code user on a MacBook with default Chrome and only one tab open got 'Error: No tab with given id 24961936' even though /mcp showed the server connected; no resolution was posted.
